Capacitance of dielectric coated cylinder of finite axial length and truncated cone isolated in free space

Capacitance of dielectric coated metallic cylinder and truncated cone are evaluated using the method of moments based on pulse function and point matching. The analysis is based on boundary condition for the potential on the conductor surface and normal component of displacement density at the dielectric-free space interface. The total free charge on the conductor surface is found from the inversion of a matrix partitioned into submatrices. Numerical data on capacitance and charge distribution are presented.
